Miscarriage is a great emotional shock to those who are eagerly preparing to become mothers, especially when the miscarriages are consecutive. Recurrent miscarriages are when there are 2 or more miscarriages with a gestational age of less than 20 weeks.

Recurrent miscarriage is the phenomenon of having 2 or more consecutive miscarriages, the fetus is expelled from the uterus before 22 weeks. In fact, the cause of recurrent miscarriages is unknown because current medical examinations and tests (in Vietnam or around the world) have not yet discovered the cause.
